SPECIFICATON forming part of Letters Patent No. 789,589, dated May 9, 1905.

Application led February 21, 1903. .Serial No. 144,385.

Be it known that I, ORLANDO V. Oa'rnu, a citizen ot' the United States, residing at Harvey, in the county ol Cook and State ot' lllinois, have invented certain new and useful Improvements in lVell-illachines, oi' which the following is a speciiication.

My invention relates to well -machincs in which the rope er cable to which a drilling or sprinkling tool isattached is carried Vtrom a rotary whaling-drum to and over an overhead pulley at the upper portion ol a derrick, so as to permit the tool attached to its free-end portion, which depends Vfrom such overhead pulley, to perform its required work, the jumping or vertical reciprocation o'li the tool being eiieeted by passingl the rope or cable about a pulley which is mounted upon a walking-beam and arranged to engage the rope or cable at a point between the windingdrum and the overhead pulley on the derrick. In machines of such character the walkingbeam, so Yfar as I am aware, has generally been arranged substantially horizontal.

Objects of my invention are to increase the length of stroke or reciprocation on the part of the tool employed, to lessen the power required for operating the vibratory beam, to place the beam as a whole nearer the derrick, and thereby shorten the length of the niachine and render it more compact, and te provide a simple, compact, and effective device :for controlling the winding-drum.

ln the accompan ying' drawings, Figure l is a side elevation ot' a portion ot a well-machine embodying my invention. Fig. 2 is a top plan view. Fig. 3 is a detail view showing the brake device employed. Fig. Lt is a side elevation as in Fig. 1l, with the pulleys l( and L omitted and connection between the beam lll and the rope or cable attained through the medium olI certain devices illustrated. Fig. 5 shows a portion olf the machine in side elevation and includes a derrick with an overhead pulley thereon.

The rope or cable A is attached at one end to a winding-d rum B, Fig. 2, and is understood to be extended upwardly therefrom to any known or suitable overhead pulley or pulley system at the upper )oi-tion ot' an ordinary derrick, illustration ot such overhead pulley A at the upper portion olI a derrick A2 being shown in Fig. 5.

The whaling-drum ,l is mounted upon a main t'ralne C and is nmmally leose--that is to say, it is loose when the driving power is disconnected from it, whereby the weight of a tool on the lree end ol the rope or cable portion which depends Ylrom an elevated pulley on the derrick will draw the rope or cable in a direction to cause the winding-drum to revolve and unwind and pay out the rope or cable, while, on the other hand, when driving' power is applied to the drum the latter will be revolved in a direction to wind up the rope or cable, so as to raise the tool from the well. As a means for alternately applying and disconnecting the driving power to and Yfrom the drum the latter is provided with a spur-gear D, and a rotary power-driven shaft 1 is provided with a powertransmitting clutch device consisting oi a pinion E, splined or keyed to slide longitudinally upon the shaft and having' a hub portion 2, provided with a loose collar 3, which is link-connected with a shifting lever F. By adjusting this lever as in Fig. 2 the driving-pinion will be lelt free to turn and pay out the rope or cable, and by reversing the lever the pinion will be thrown in clutch with the relatively large spur-gear, whereby power `trom the continuonsly-running shalt will be imparted tothe drum,which will thereupon be driven in a direction to wind up the rope or cable, and thereby raise the tool Ylrom the well.

The rotary power-driven counter-shaft l is arranged parallel with the axis of the winding-drum, and the latter has one. oil,l its journals or axle ends provided with the spur-gear l) and also projected therefrom to al'lord a bearing lor a loose collar fl, upon which the shifting lever F is pivoted. The spur-gear l is also provided with aprojecting hub portion i 5, having' a plane peripheral faceaud 'forming a brake-wheel for a brake-band 6, which, as shown in Fig. 3, can be operated by a bandtightener G. The brake device thus arranged can be employed when the shifting drivingpinion is tln'own out of mesh with the relatively large spur-gear on the winding-drum, so as to regulate the speed of the descending tool, and when the pinion is tln'own into mesh with the spur-gear the drum will operate to wind up the rope or cable without sudden jerk and strain upon, and therefore without injury to, the rope or cable, it being observed that with long lengths of rope or cable the avoidance of sudden jerk and strain at the initial movement is amatter of considerable importance, particularly where there happens to be some slack in the rope or cable portion between the drum and the tool.

The countershaft l is operated from a rotary power-driven shaft 7, having secured thereon a large friction-wheel 8, which engages a smaller friction-wheel 9, secured upon the counter-shaft l, this arrangement vbeing simple and compact and avoiding a multiplicity of toothed gear-w heels with their wellknown objectionable features, such as expense in making and liability of breakage of teeth.

In order to alternately pull and slacken the rope or cable, so as to produce a jumping motion on the part of the tool and to attain a relatively large extent of such jumping or re eiproeating movement, a vibratory beam H is pivotally supported at one end portion upon the main frame C and arranged to rise from its pivotal support, as in Figs. l and 4. This vibratory bea-m is connected with the rope or cable in a way to exert a lateral pull upon the portion of the rope or cable between the winding-drum and the overhead pulley at top of the derrick and in a direction away from the derrick when the beam swings in a direction away from the derrick and to slacken up on the rope or cable, so as to permit the tool to drop when the beam is swung toward the derrick. The vibratory beam H is operated from the main driving-shaft 7 by means of an eccentric I, which is secured upon suoli shaft and arranged between the beam and a yoke-strap l', secured upon the latter. By thus arranging the beam to extend upwardly from its pivotal or fulcral support it can be so nearly balanced as to permit the application of the actuating' power relatively near its pivotally-supported lower end. vWith such arrangement the beam forms a long lever with the power applied between its ends, so as to form a short arm, which is fulcrumed on the main frame at a point below the power, and a long arm, which extends upwardly from the point at which the power is applied and which connects with the rope or cable, theV stroke of the drilling-tool being' proportional to the extent of swing on the part of the lever and the point of connection between the lever and the rope or cable, which in both Figs. l and a is ata pointconsiderablyhigher than the point at which the power is applied to the lever.

In Figs. l and 5 the vibratory beam H is provided with an idler sheave or pulley K, supported upon the upper portion of its long arm, and the rope or cable from the windingdrum is carried therefrom to and about an idler sheave o1' pulley L on standard C of the main frame G, thence to and about the pulley K on the vibratory beam or lever H, and thence up to an overhead pulley A, Fig. 5, at the top ofthe derrick A2. By applying the operating power to this beam or lever at a point relatively near its lower pivotally-supported end and applying pulley K at a point relatively high up on the upwardly-extending long-arm portion of such beam or lever the arc which is traversed by the upper end of the beam or lever will be of much greater extent than the arc traversed by such beam or lever at the point where power is applied, and hence with a comparatively limited extent of throw on the point of an eccentric the pulley K will have a comparatively wide range of bodily swing, which is particularly effective in spudding, where a considerable extent of rise and drop on the part of the spuddingtool is desirable. The arrangement of the beam or lever H relatively to the drum and derrick also permits the action of the beam or lever to exert a comparatively large extent of pull on the rope ror cable, it being obvious that when the beam is swung to the right or away from the derrick it will draw a portion of the rope or cable downwardly and away from the top of the derrick and also draw a portion of the rope or cable in a direction laterally away from the derrick, whereby when the beam or lever is swung in areverse direction it will slacken up on said two portions of the rope or cable and permit the tool to drop to an extent proportionally to the extent to which such rope or cable portions had been drawn away from the derrick by the beam or lever.

In Fig. 4 the vibratory beam or lever H is connected with the rope or cable through the medium of a second vibratory beam or lever H, which is actuated from the vibratory beam or lever H by a link or pitman connection M and a rope or cable N, attached at one end to the beam or lever H and attached at its opposite end to a member lO, with which the rope or cable A has a shifting connection, the member l() being' a guide device such as a sheave or` as shown, a shoe adapted to embrace said rope or cable A. lVith this arrangement the vibratory beam or lever H is pivotally supported at its lower end and arranged back of and in position generally corresponding with the vibratory beam or lever H, and in order to adjustably vary the stroke the connection between the link or connecting rod or pitman M and the vibratory beam IOO IIO

IIS

or lever H can be adjustably shifted along the latter--as, for example, the link M can be attached to the beam or lever Il by a pivot 1l, inserted through some one of a series ol? holes 12 in such beam or lever-"and in like manner a clevis 13, to which one end ot the pull rope or cable N is secured, can be adjustably attached to the vibratory beam or lever H by a pin or pivot 14; inserted through some one ot' the said series ot' holes l2 in such beam or lever. By this arrangement the extent o'f vertical movement on the part ot' the tool can be considerably augmented, and by adjusting the connection between the link M and rear vibratory beam or lever H the extent ot' such movement can be varied.

As the work progresses the rope or cable can be caused to pay out from the windingdrum by loosening the brake-band upon the brake-wheel, so as to permit the windingdrum to run loose, and when desired the pinion E can be shifted into mesh with the spurgear D for the purpose of causing the driving` power to operate the winding-drum in a direction to wind the rope or cable thereon, and thereby raise the tool from the well.

Yl. have in following Claim l described an improvement common to both Figs. l and 4, a prominent feature of said Fig. 4 being the rope or cable N, which may be termed a "jerk-line, arranged to exert lateral pull upon the main rope or cable A. Obviously this lierk-line could be attached to beam H and beam H/ dispensed with, or beam H can be dispensed with and an ordinary strap for eccentric I can be connected with the beam li, the jerk-line being attached to the latter.

l/V hat I claim as my invention is l. Yln a wellmachine, a substantially upright vibratory beam pivotally supported at its lower end; means for operating the beam consisting ot' an eccentric applied to it at a point whereby the length ot' beam portion above the eccentric is greater than the length of beam portion below such eccentric; a winding drum arranged between the vibratory beam and tliederrick; a rope or cable which is carried upwardly from the winding-drum to and over an overhead pulley at the upper portion ofthe derrich; and connection between the upper portion of -the vibratory beam and the portion of rope or cable between the winding-drum and the overhead pulley on the dcrricli, said connection being arranged to permit the swing of the vibratory beam in a direction away 'from the derrick to exert a lateral pull upon said rope or cable portion at a point between the winding-drum and the overhead pulley on the derrick.

2. 1n a well-machine, a winding-drum; a rope or cable passing Yfrom the winding-drum to an overhead pulley; a substantially upright Vibratory beam provided with a shcave about which the portion et' the rope or cable between the winding-drum and the overh fad pulley passes; and a device Vlor vibrating the beam applied thereto at a point below the sheave thereon; the beam being pivotally supported below the device for causing it to vibrate. and being arranged to permit its sheave to exert a lateral pull upon the rope or cable during the swing oi' such beam in one direction.
